PUTTYING-TOOL.

SPECIFICATION forming part of Letters Patent No. 760,027, dated May 17,1904..

Application filed July 9.1903. Serial No. 164,885. (No model.)

To all whom it may concern:

, declare the following to be a full, clear, and

exact description of theinvention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to an improved puttying-tool of that character inwhich means are employed for automatically forcing the putty from areservoir out through a nozzle onto the article being glazed, the feedof putty being regulated by the operator so as to eject the amountrequired for use.

It has for its object to provide a tool of this character embodying anumber of improved features of construction, among them an im proveddetachable nozzle and simple and effective operating means under thecontrol of the operator for feeding out the putty, whereby theefficiency of the tool is increased and a form of tool provided whichmay be readily and conveniently manipulated by the operator.

With these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be hereinafter more fully described, and particularly pointedout in the appended claims, reference being had to the accompanyingdrawings, in which Figure 1 is a side elevation of a puttying-toolembodying my invention. Fig. 2 is alongitudinal section of the same.Fig. 8 is a crosssection through the nozzle on line 8 3 of Fig. 2. Fig.4 is a cross-section through the rack-bar on line a 4 of Fig. 2, andFig. 5 is a detail view of the power-handle and connections.

In the embodiment of my invention I provide a reservoir 1 open at itsrear end and closed at its front end by a head or front wall 2, the rearportion of the reservoir preferably being cylindrical and the frontportion having a beveled or inclined wall 3 to guide the contained puttyto the nozzle 4:, as hereinafter described. Operating in the reservoiris a follower or piston 5, to which is connected a rearwardly-extendingrack-bar 6 and which when forced forward in the reservoir feeds theputty to the nozzle 1. As shown, the nozzle 4: is of triangular form andtapering, so as to eject the putty in such shape as to conveniently 1111the space to be glazed and is provided with a socket 7 for the receptionof the knife 8, by which the putty is applied, the knife beingdetachably secured in position by aset-screw 9. The nozzle is carried bya bracket-plate 10, which has an opening coinciding with the bore of thenozzle and is formed with beveled edges 11 to lit within a beveled ordovetailed guideway or receptacle 12, riveted or soldered on the head 2.The lower end of this receptacle forms the entrance thereto throughwhich the bracket-plate 10 is inserted and removed, so that in the useof the knife 8 the applied pressure will serve to force thebracket-plate more firmly in position, and thus prevent the nozzle frombecoming loosened or detached from the holder or guideway 12. The holderor guideway 12 may be formed by a plate secured to the head 2 and havingan opening coincident with the feed-opening in said head and three ofits sides turned over to form the guideway for the bracket-plate.

Fixed to the top of the reservoir by means of a tang 13 is a stationaryhandle 14, which projects from the reservoir, and located be low saidstationary handle is a movable or power-applying handle 15. This handle15 is provided with a bell-crank 16, formed by a tang extendingoutwardly therefrom and bent into form, said bell-crank being pivoted atits angle by a pin 17 between cars 18 on a segmental-shapedbracket-plate 19,detachably se- 8 5 cured to the under side of thereservoir,where by the handle 15 and its connections may be removed forrepairs, &c., whenever required. The upwardly-extending arm of thisbellcrank lever 16 has a back-turned lug or pro- 9 jection 20, to whichis pivoted a pawl or dog 21, adapted to engage the teeth of the rackbar6. This dog or pawl lies above the guideway 22, formed upon the saidupwardly-extending arm of the bell-crank lever, which guideway serves toretain the rack-bar in a determined position and to guide it in itsmovements, thus preventing the piston from binding against the innerwall of the reservoir.

In the operation of the tool, assuming the reservoir to be supplied withputty, it will be understood that upon the upward pressure of the handle15 the vertical arm of the bellcrank lever will be forced forward,carrying with it the pawl 21, which will engage one of the teeth on therack-bar and force the piston forward a predetermined distance, thusexpelling a certain amount of putty from the nozzle, which putty maythen be applied by the knife upon a proper manipulation of the tool.Upon the release of the handle 15 the latter then drops by gravity downto its normal position, thus drawing back the pawl the space of onetooth, so that an ensuing upward movement of thehandle 15 will effectthe discharge of a similar quantity of putty in like manner. From thisstatement the operation of the tool will be readily understood, and itwill be seen that by the described construction and relation ofthe partsthe retraction of the powertransmitting device is not only automatic,but that through the bell-crank lever a great leverage may be applied toforce the putty forward, thus allowing a somewhat contracted nozzle tobe used to exert enough working action on the putty to smooth it out andmake it soft for free application and use. The detachable connection ofthe nozzle allows this part of the tool to be conveniently detached forthe removal of hardened putty when occasion requires.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A tool of the character described, comprising a reservoir having anoutlet, means for feeding the material from the reservoir to saidoutlet, and a nozzle having a slidable detachable connection with thereservoir, and carrying an applying device, substantially as described.

2. A tool of the class described, comprising a reservoir having anoutlet and a nozzleholder forming a guideway communicating with saidoutlet, said guideway having its entrance below the outlet, means forforcing the material through said outlet, and a nozzle having abracket-plate detachably engaging said holder and carrying an applyingdevice so arranged that the working pressure thereon will be in thedirection of movement of the bracketplate in entering said guideway,substantially as described.

3. In a tool of the character described, the combination of a reservoir,a piston therein provided with a rack-bar, a fixed handle on one side ofthe reservoir, a movable handle on the opposite side of the reservoir, abellcrank lever pivoted to the reservoir, said bellcrank lever havingone arm connected to the movable handle and the other arm formed with aguideway and a supporting-lug projecting from one side of said guideway,and a pawl carried by said lug and arranged above the guideway to engagethe rack-bar, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
